可能重复：
java3D lib 配置问题

我想在Ubuntu上使用 JAVA 制作一个 3d 游戏，因此我j3d-1_5_2-linux-i586.zip从下载并http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-java-client-419417.html#java3d-1.5.1-oth-JPR提取了它。在Eclipse中，我在 Eclipse 中添加了 3 个 jar ../j3d-1_5_2-linux-i586/lib/ext/，然后编写了这段代码

import com.sun.j3d.utils.universe.SimpleUniverse;
import com.sun.j3d.utils.geometry.ColorCube;
import javax.media.j3d.BranchGroup;

public class Hello3d {
    public Hello3d() {
        SimpleUniverse universe = new SimpleUniverse();
        BranchGroup group = new BranchGroup();
        group.addChild(new ColorCube(0.3));
        universe.getViewingPlatform().setNominalViewingTransform();
        universe.addBranchGraph(group);
    }

    public static void main(String[] args) {
        new Hello3d();
    }

}

得到这些错误

Description Resource    Path    Location    Type
Access restriction: The constructor SimpleUniverse() is not accessible due to restriction on required library /home/emil/Downloads/j3d-1_5_2-linux-i586/lib/ext/j3dutils.jar    Hello3d.java    /Checker3D/src  line 7  Java Problem

更像是 我将“ Forbidden reference (access rules)”下的“ Deprecated and restricted API”从“ **Error**”设置为“ **Warning**”。

在建筑上 我得到了

    at Hello3d.main(Hello3d.java:15)

在Run--->Run Configuration ---> JAVA applications--->(x=)arguments--->VM Argiments中，我添加了

-Djava.library.path=$LD_LIBRARY_PATH:/home/emil/Downloads/j3d-1_5_2-linux-i586/lib/i386/

我得到了那个错误

这是你的答案干杯！

Windows -> 首选项 -> Java -> 构建路径 -> 用户库 1. 新建：J3DAll，2. 添加 JAR .. 在 ..\jre6\lib\ext\j3dcore.jar、j3dutils.jar、vecmath 中选择所有三个。罐

Project -> Properties -> Java Build Path -> Libraries Add Library .. -> User Library -> 接下来选择 J3DAll Finish Project -> Properties -> Java Build Path -> Order and Export Top J3DAll
